2009 ISX 400 sputters during acceleration but cleans up

Customer Question

2009 ISX 400 sputters during acceleration but cleans up around 1500RPM. The other day, code popped up for turbo actuator. Replaced and calibrated turbo and actuator. Found turbo was locked up. Hooked up to insite and found cylinder 6 failed. Replaced #6 injector, helped a lot but there is still the sputter during acceleration.

good morning my name is ***** ***** I will assist

when we find a failed injector, especially with a failed turbo, we always recommend replacing all 6 injectors. in your case, you may have more than one that has failed but has not coded yet. if I were you, I would consider replacing the other 5 injectors. and changing the fuel filters.
